ZeeLung is a biomass carrier that supports the growth of a biofilm
the carrier material “breathes” and transfers oxygen to the biofilm at
very high efficiency without the use of bubbles

New Total Phosphorus (TP) Effluent Limit
Annual Average TP of 1.0 mg/L
Rapid population increase affect on per capita Influent Loading:
BOD increase
2001 Avg. Loading: 157 mg/L
2012 Avg. Loading: 215 mg/L
Industrial Dischargers
High strength: 10% of BOD capacity
Low flow: 1% of Hydraulic capacity

Site Constraints
Existing treatment site is built-out
Any significant capacity increase will require construction of a new treatment facility west of Blackberry Creek

SND in the Zeelung zone reduces the nitrate loading to anaerobic zone which improves enhanced biological phosphorus removal (EPBR) performance
Increase of BOD treatment capacity within existing footprint
Minimizes impact of industrial loads on treatment capacity
ZeeLung implementation cost < 25% new treatment facility
Increase in capacity without increase in energy consumption
Implement with EBPR within 18 months

Start-up ProtocolStart-up Protocol
Mixed liquor and influent wastewater introduced on November 15, 2017
Operated in Parallel to initially limit flow to MABR
Influent was initially brought in at 50% of the design load to establish biofilm
Influent loading was stepped up to the design loading over a 6 week period.
